      abstract     = {Polymers adsorbed on nanoparticles (NPs) are important
                      elements that determine the dispersion of NPs in polymer
                      nanocomposite (PNC) films. While previous studies have shown
                      that increasing the number of adsorbed polymers on NPs can
                      improve their dispersion during the drying process, the
                      exact mechanism remained unclear. In this study, we
                      investigated the role of adsorbed polymers in determining
                      the microstructure and dispersion of NPs during the drying
                      process. Investigation of the structural development of NPs
                      using the synchrotron vertical-small-angle X-ray scattering
                      technique revealed that increasing polymer adsorption
                      suppresses bonding between the NPs at later stages of
                      drying, when they approach each other and come in contact.
                      On the particle length scale, NPs with large amounts of
                      adsorbed polymers form loose clusters, whereas those with
                      smaller amounts of adsorbed polymers form dense clusters. On
                      the cluster length scale, loose clusters of NPs with large
                      amounts of adsorbed polymers build densely packed
                      aggregates, while dense clusters of NPs with small amounts
                      of adsorbed polymers become organized into loose aggregates.
                      The potential for the quantitative control of NP dispersion
                      in PNC films via modification of polymer adsorption was
                      established in this study.},
